[QUOTE="Opa-lopa, post: 2441842, member: 108809"] Having measured engraving pressures on numerous small call bullets, I can tell you that velocity consistency is limited by shot-to-shot variations in bullet engraving pressures. Are there can combinations of powder/primer/projectile that give low velocity variations? Sure there are. Doing a single shot ladder test is a sure way to get fooled about which combination gives the lowest velocity variation & smallest groups. I’ll say it again: velocity “nodes” determined by a single shot ladder test are meaningless. [/QUOTE]
